Couple of issues wih my Mamba Max

Hippie; You did removed the red wire from the ESC, right?
Seems to me like the UBEC is loosing signal.. Either that, or the receiver is not working properly. That thermalling you had last time is result of the fan going off-line, but IMO it should run longer without a fan. It can be the timing indeed. Sometimes a softer timing makes the motor hotter than it was.. (noticed this with my schulze/plettenberg setup) if i recall this correct; a 2 pole (hacker) needed a harder timing than the 4 pole plettenberg.
